Abstract
The utility model relates to a kind of four blade milling cutters, including the knife handle being mounted on collet chuck and the cutter head for being located at knife handle one end, spiral side cutting edge there are four being set on the cutter head, one end of the cutter head is additionally provided with four end swords, the relief angle of every one end sword is arc-shaped relief angle, and the tangential direction of arc-shaped relief angle and the angle of horizontal direction are 13 °.The relief angle for holding sword is set as arc-shaped relief angle, the tangential direction of arc-shaped relief angle and the angle of horizontal direction are 13 °, and the intensity of end sword in this way increases, in metal cutting process, it is greatly improved the cutting output and cutting speed of cutter, to improve production efficiency, reduces production cost.
Description
Technical field
The utility model relates to cutting-tool engineering field, especially a kind of four blade milling cutters.
Background technique
Milling cutter is common tool in machinery production manufacture field, cutting-tool's used life, workpiece surface quality with
And processing stability is the principal element for measuring cutter quality, and cutter these performances is fine or not in addition to related with the material of cutter
Outside, the structural parameters of cutter are depended mainly on.Existing milling cutter is straight line relief angle, due to straight line relief angle and tool orthogonal rake composition
Blade is thiner, and in metal cutting process, cutting edge abrasion is very fast, and cutter life is low, with the increasing of cutter usage amount
Add, cost increases therewith.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of four blade milling cutters, it is intended to after solving existing milling cutter
Angle is straight line relief angle, and cutting edge abrasion is very fast, cutter life low problem.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of four blade milling cutters, including installation
Knife handle on collet chuck and the cutter head for being located at knife handle one end, set that there are four spiral side cutting edges on the cutter head, described
One end of cutter head is additionally provided with four end swords, and the relief angle of every one end sword is arc-shaped relief angle, the tangential direction and water of arc-shaped relief angle
Square to angle be 13 °.
Further, the surface of the end sword is equipped with graphene layer.
Further, the other end rounded corner of the knife handle.
Further, the helical angle of the side cutting edge is 21.5 °.
Further, the surface of the side cutting edge is equipped with purple titanium coating.
Compared with the existing technology, a kind of four blade milling cutter provided by the utility model, after the relief angle for holding sword is set as arc-shaped
Angle, the tangential direction of arc-shaped relief angle and the angle of horizontal direction are 13 °, and the intensity of end sword in this way increases, in metal cutting
Cheng Zhong, is greatly improved the cutting output and cutting speed of cutter, to improve production efficiency, reduces production cost.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the structural schematic diagram of four blade milling cutter provided by the utility model；
Fig. 2 is the right side view of Fig. 1.
Specific embodiment
Now in conjunction with attached drawing, elaborate to the preferred embodiment of the utility model.
As illustrated in fig. 1 and 2, the utility model provides a kind of four blade milling cutters, including the knife handle 10 being mounted on collet chuck and sets
Cutter head 20 in 10 one end of knife handle, sets that there are four spiral side cutting edges 21 on cutter head 20, and one end of cutter head 20 is additionally provided with
Four end swords 22, the relief angle of every one end sword 22 are arc-shaped relief angle 1, the tangential direction of arc-shaped relief angle 1 and the folder of horizontal direction
Angle is 13 °.It holds the intensity of sword 22 to increase in this way, in metal cutting process, is greatly improved the cutting output and cutting speed of cutter
Degree reduces production cost to improve production efficiency.
In the present embodiment, the other end rounded corner 2 of knife handle 10.When 10 clamping of knife handle is in collet chuck, rounded corner 2 can subtract
Friction between small knife handle 10 and collet chuck, extends the service life of collet chuck, save the cost.The surface of end sword 22 is coated with graphene
Layer, can increase the intensity of end sword 22, prolong its service life.
Further, the helical angle of side cutting edge 21 is 21.5 ° by the way that helical angle is set as 21.5 °, when clast is discharged
The abrasion of cutter is reduced, is beneficial to the protection to cutter, prolongs the service life, while the surface of side cutting edge 21 is equipped with purple titanium
Coating can increase its intensity, prolong its service life when carrying out Milling Process.
It should be understood that above embodiments are only to illustrate the technical solution of the utility model, it is rather than its limitations, right
For those skilled in the art, it can modify to technical solution illustrated in the above embodiments, or to part of skill
Art feature is equivalently replaced；And all such modifications and replacement, it all should belong to the protection of the appended claims for the utility model
Range.
